Re: Petrof lyre bolts

[Douglas Gregg]

Hi all,
I just acquired a Petrof III 6'4" 1998 grand. The last movers lost the
lyre bolts. When I had another of these, I believe they had a big
cast-in wing nut top on the bolt. I would like to get new ones for it.
Does anyone know where I could order them?

Cheers,

Hi, they must be ISO threads . you may be able to have the dimensions. very probably they are given on the Petrof web site, in the part where they sell parts and accessories. (pdf files)

let me know if you do not find them.

PETROF U.S.A., LLC - Petrof - upright pianos and grand pianos since 1864

I tried the Petrof.com site but there is no parts list. Unless it is
in slovac and I don't read that.

I can call and try to get it from the central office in CA. But Isaac
might have them in his junk box. I was hoping that might be the case.
I will send the thread size and length to Isaac.
Glad to have made contact in Chicago and Seattle.

Hi Greg, 

Unfortunately I do not have a spare of those.

You may see them there :

http://www.petrof.com/files/nahradni_dily/nahradni-dily-kov.pdf

At first sight those are 8 mm or 10 mm standard ISO thread for that diameter.

May be the reference (203400) can help you to order the parts .

Best regards

Isaac,
Thanks for checking. I will likely do as you suggested and get them at
an auto parts store with a hex head. Thanks again.

Hi, Doug !
Switching to Hex Head works the best, and GWU...
Best wishes..

.... and then cut a slot in the head to facilitate the use of a screwdriver.  This will keep the piano movers from calling you names when they find they don't have the exact socket or wrench to remove the bolts.  Just simple hacksaw cut will suffice.

or solder a big washer in the saw line.

I was going to put a slot in the hex. I know from experience how
frustrating that can be.
I do a lot of moving.
